Bahrain Welcomes Autumn with Cooler Temperatures and Clearer Skies

Bahrain is set to enter the autumn season tomorrow, Monday, 22 September, with forecasts indicating a drop in temperatures below 40°C for the first time this year. Alongside the cooler weather, humidity levels are expected to decrease, bringing a relative improvement in atmospheric conditions.

According to the Meteorological Directorate at the Ministry of Transportation and Telecommunications, a gradual change in weather will begin tomorrow. Maximum temperatures are expected to remain below 40°C, with humidity not exceeding 70%, while minimum temperatures will drop to around 27°C.

The Directorate also noted that northwesterly winds will remain active across the kingdom until Thursday, 25 September. Wind speeds are expected to vary from moderate to active, occasionally reaching strong levels, which may cause higher sea waves and raise dust in open areas.

Bahrain has already witnessed a noticeable temperature decline over the past week, and the continued activity of the northwesterly winds is expected to make the evenings feel more comfortable due to reduced surface humidity. Authorities have advised residents and visitors, particularly those venturing out to sea, to exercise caution and stay updated with official weather alerts.

Astronomer Ali Al-Hajri explained that the approach of the autumnal equinox, caused by the tilt of the Earth’s axis, will gradually reduce the midday sun’s altitude, resulting in a slow daily drop in temperatures by approximately 0.1°C. Nighttime temperatures are expected to fall from 30°C to 27°C, while daytime highs will decrease from 38°C to 35°C. Al-Hajri added that the nights will begin to feel cooler by late October, with daytime cooling continuing until the end of November.

He further noted that the transition from summer to winter occurs gradually and often goes unnoticed at first. However, its effects are visible in daily life, including the spread of seasonal illnesses among children and the elderly, increased migratory bird activity, the start of various planting and harvesting seasons, and the appearance of specific fish species that attract local fishermen.
